Definitions

• the invention relates to a process for the production of electrically conductive polymers with electrical conductivity values greater than 10 -2 S / cm and their use in the electrical industry for the production of solar cells, for the conversion and fixation of radiation and for the production of electrical and magnetic switches and for antistatic equipment of plastics.
• the organic polymers from the heteropolyphenylene series differ from the polyphenylenes in that there are heteroatoms or groups containing heteroatoms between the aromatic ring systems. These polymers are described, for example, in "Macromolecular Synthesis", 6, (1978), pages 45 to 48.
• the preparation of the organic polymers from the series of polyacetylenes by polymerization of acetylene is also known. It is, for example, in the works of Hatano in "J. Chem. Soc. Japan, Ind. Chem. Sect.” 65, (1962), page 723 ff. And by DJ Berets et al. "Trans. Farad. Soc.” 64, (1968), page 823 ff. Even in newer publications by H.
• the invention had for its object to convert the known organic polymers from the series of polyphenylenes, heteropolyphenylenes or polyacetylenes by additions into electrically conductive polymers with electrical conductivity values greater than 10 -2 S / cm and, moreover, to stabilize them decisively against oxidative damage and significantly increase the processability and range of applications.
• This object is achieved in that the organic polymers from the series of polyphenylenes, heteropolyphenylenes or polyacetylenes with the exclusion of water moisture and oxygen from 0.1 to 95% by weight, based on the polymer, black phosphorus and 0.5 to 25 % By weight, based on the organic polymer used, of a strong Lewis acid with pk s values of -10 to +14.

• the electrical conductivity values are measured in S / cm at 30 ° C, the measurement itself is carried out according to the method of F ,. Beck, "Bunsen Society reports, physical chemistry” 68 (1964), pages 558 to 567.
• the electrical conductivity values of the conductive polymers according to the invention is greater than 10 -2 S / cm.
• the organic polymers are 0.1 to 95% by weight, based on the weight of the polymer, black phosphorus and 0.5 to 5% by weight, based on the polyphenylene used , a strong Lewis acid with pk s values from -10 to +4.
• the additives are incorporated in the absence of moisture (water) and oxygen (air), so it is preferably carried out under an inert gas-argon atmosphere. If necessary, auxiliary liquids such as tetrahydrofuran, dimethoxyglycol, nitromethane or methylene chloride are used, which are removed in vacuo after incorporation at temperatures below 30 ° C.
• the additives mentioned allow electrical conductivity increases of several orders of magnitude to be achieved.
• the starting conductivity of the organic polymers was 10 -12 S / cm.
• the organic polymers according to the invention have starting conductivities of less than 10 -12 S / cm, but after the addition of the additives according to the invention give conductivities greater than 10 -2 S / cm.
• the electrically conductive polymeric systems produced according to the invention with electrical conductivities greater than 10 -2 S / cm are for the antistatic finishing of plastics, for the production of solar cells, for the conversion and fixation of radiation and for the production of electri shear and magnetic switch suitable.
• the addition of the strong Lewis acid with black phosphorus creates so-called p-conductors (cf. "J. Chem. Education", 46, (1969), No. 2, page 82).
